The demand for electrical energy increases day by day. Hence, energy conservation is an important occurrence nowadays, which is why mitigation of distribution system losses is considered one of them. For an efficient distribution system, restructuring of the existing system is happening consequently. In this study, the restructuring of radial feeders is integrated into a multi-loop distribution system, and power loss reduction is achieved in the system by using a cost-effective and reliable power flow controller, that is, the Sen transformer. The objective of Sen transformer is to eliminate circulating loop currents from the multi-loop distribution system by injecting compensating voltage into the feeders. The realization of the power loss reduction through Sen transformer is achieved by compensating the voltage reactance drop of the feeders and eliminating loop current from the system. The prototype laboratory setup is established to validate the proposed method and the results are presented in this study. The experimental setup is established first for radial distribution feeders, secondly for multi-loop distribution feeders, and lastly for multi-loop distribution feeders with the installation of Sen transformer. When compared to the radial system and multi-loop system, the installation of Sen transformer results in around 40% and 30% reduction in power loss, respectively.
